We don't have the same machine, but on mine, the mask resistance is called "System One Resistance". If I am scrolling down the clinician menu quickly and don't hover over it, all I see is "System O" and a value of zero, so I didn't realize it was mask resistance until I happened to stop at it recently and checked to see what values other than 0 were available for settings. That's when I discovered that the other values were X1, X2, etc.

Do I need to change this? Can someone explain how these settings affect the pressure delivered by the machine?

All I know is that different types of masks have a "resistance setting" that the machine should be set at, but I'm not clear on what happens if you don't use the correct setting.

I'm the opposite of an expert but...if I'm not mistaken the Wisp is a PR product, so according to what Ghost1958 wrote the setting would be X1. I have no idea what difference it would make if you changed it.

In my case, I'm going from one Swift (non-PR) thingy to another. Both the nasal pillows and the Nano use the same vent, which is built into the short hose that they share, as ratherberiding indicated. Since this setting is all about the basic leak/vent rate of the mask or pillows, and that doesn't change in my particular case, I've decided to leave it alone where the tech set it.

The Nano does make me look like Peppa Pig, so my granddaughter will approve.
